2 Claims. (01.101-849) In printing presses the inking rollers are genthe ordinary and well known construction. The orally arranged in a fixed position with respect to numeral 14 designates one member of a supportthe surfaces of the printing plate or type, and in ing. bearing or bracket provided with a semi-cirthe larger type of presses the rollers are very cular bearing 15, and this bracket 1 1 may be s e- 5 heavy and considerable frictiori is caused in the cured to any portion of the printing press for ad- 0 bearings thereof, with the result that considerjustment in different planes for positioning an able power is necessary to cause thernlto function inking roller journaled therein toward and away properly; it one ofthe objects of the present from the periphery of the cylinder by means of invention to provide improved roller bearing an arm 16 in which is provided a slot 17, and

' 1n sockets in, which the ends of, the inking rollers through which slot a fastening bolt 18 passes, a

are journaled, with the result that the speed of nut 19 being provided on the belt for securing the operation of the machine will be materially inbracket in position.

The roller bearings ig igfig accnmance W e p p s 32 are held agalnst displacement with respect 45 Figure 2 is a, left hand end elevation of to the socket 31 in any suitable manner such as ure 1 by means of a split spring ring 34 engaging in a Figure 3 is a detail sectional view with parts recess 5 in the Wall of the Socket 31, and rests Omitted and with parts broken away and as against a plate 36 which encompasses the sleeve taken on line Figure 33 and forms a closure for the socket 31. This 59 Figure 4 is a detail sectional View taken on Plate 36 forms a Closure the portlon of the line 4 4, Figure 2, with parts omitted socket in which the rollers 32 are located and Referring more particularly to the drawing th renders it possible to fill the socket with lubricatnumeral 10 designates generally the supporting ing materialstructure of a printing press, 11 the printing cyl- The extremities of the axles or shafts 37 of the inder and 12- 13 operating gears therefor, all of printing or inking rollers 38 are eccentrically mounted in the bearing member 27 and are inserted into the sleeves 33 and project through the portions 28 of the bearing members 27 and the axles 37 frictionally fit within the sleeves 33, so that upon rotation of the axles the sleeves will also be rotated.

It will therefore be manifest that with this improved construction there is provided a roller bearing socket in which the ends or axles of the printing rollers are journaled and by reason of these roller bearings the friction between the printing rollers and the bearings will be materially reduced and less power will be required to operate the machine.

It has been found that by reason of the fact that these printing rollers 38 are constructed of a composition, they become very hot when the use thereof has been extended, and they become soft, with the result that when the press is idle, if the rollers are allowed to remain in contact with the cylinder or printing surface as and when they become cool, fiat portions will be formed in the rollers or the surfaces thereof and they will become distorted. Therefore, in order to provide a means for maintaining and holding the rollers out of contact with the printing surfaces when' the press is idle, and thereby avoid the necessity of lifting the rollers out of position, the axle of the rollers have been eccentrically mounted in the bearings 27. By loosening the thumb nuts 26 and rotating the bearings 27 in the brackets by means or" the portion of the bearings which project beyond the brackets it will be manifest that owing to the eccentric mounting of the axle 37 the roller will be bodily moved away from the cylinder and may be maintained in such position to permit them to cool. When it is desired to again employ the rollers the bearings 27 are again rotated in the brackets to properly position the inking rollers with respect to the cylinder. Obviously this means may be utilized in order to ob tain the desired pressure of the inking rollers upon the cylinders.

Furthermore the slot and bolt connection 1'7--l8 between the bracket and the frameof the press will serve as a means for also varying the position of the inking rollers with respect to the cylinder, that is the bracket may be adjusted to cause the roller to move toward and away from the cylinder, or the bracket may be adjusted about the bolt 18 as a pivot.

While the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.

What is claimed as new is:

1. In combination, in a printing press, a printing cylinder, an inking roller, a supporting bracket for the roller, said bracket embodying two members hinged together to form a bearing seat, a bearing for the roller within said seat, a portion of the bearing being reduced to receive the bracket walls, one end of the bearing projecting beyond the bracket to form a hand grip for rotating the bearing in the bracket, the roller shaft being eccentrically mounted in said bearing, and means for clamping the bracket members together to frictionally bind said bearing against rotation in the bracket, said bearing being freely rotatable in said bracket when the clamping eiTect of the bracket members is released, to permit the roller to be quickly moved laterally away fromthe said cylinder.

2. In combination, in a printing press, a printing cylinder, an inking roller, a supporting bracket for the roller, said bracket embodying two members hinged together to form a bearing seat, a bearing for the roller within said seat, a portion of the bearing being reduced to receive the bracket walls, one end of the bearing projecting beyond the bracket to form a hand grip for rotating the bearing in the bracket, the roller shaft being eccentrically mounted in the bearing, means for clamping the bracket members together to frictionally bind said bearing against rotation in the bracket, said bearing being freely rotatable in said bracket when the clamping effect of the bracket members is released, to permit the roller 5 to be quickly moved laterally away from the said cylinder, there being a slot in a portion of the bracket, and a bolt passing therethrough for securing the bracket in position, said bolt and slot serving to permit the roller to be bodily adjusted toward and away from the cylinder and also about said bolt as a pivot.
